The bill amends Chapter 27-20.8 of the General Laws, introducing a new section that establishes a co-pay cap for prescription asthma inhalers, devices, and equipment. Specifically, it mandates that health plans providing coverage for these items must limit the out-of-pocket expense for covered individuals to no more than twenty-five dollars ($25.00) for a thirty-day supply. Additionally, the coverage for these items will not be subject to any deductibles. The bill also clarifies definitions for "prescription inhaler," "prescription devices," and "prescription equipment," and allows health plans to reduce cost-sharing below the specified cap.

Furthermore, the bill stipulates that prior authorization policies can only be used to confirm medical necessity for prescribed items, and it grants the office of the health insurance commissioner the authority to enforce compliance with these provisions and to create necessary regulations. The act is set to take effect on January 1, 2026.
